TRANSPORTATION, STORAGE, AND DISCHARGING VESSEL.

SPECIFICATION forming part of Letters Patent No. 506,840, dated October 17, 1893.

Application filed July 5, 1892.

To all whom it may concern.-

Be it known that I, FRANK H. BRIGGS, a citizen of the United States, and aresident of Cleveland, county of Cuyahoga, State of Ohio, have invented certain new and useful Improvements in Transportation and Storage Vessels, of whichI hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in vessels for coaling or other storage and for transporting purposes, from which the material is to be delivered in known or variable quantities, with the object in view of accurately measuring material discharged and thus preventing doubt or dispute, and in saving time and in economy in discharge.

My invention consists, primarily, in a vessel hull provided with stationary receptacles filling any portion of the hull desired, and adapted to receive and discharge large portions of the cargo or the whole cargo, while a further feature of the invention is found in one or more independent receptacles attached to oscillating scale lever mechanism whereby small portions of the load may be discharged and accurately weighed.

My invention further consists in the improved mechanism for operating the discharge gates at the base of pockets and in the various details of construction and combination and arrangement of parts, as hereinafter described, shown in the accompanying drawings, and more specifically pointed out'in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a boat showing the carrying portion in vertical central section.

Fig. 2 shows a plan of vessel carrying the improved forms of receptacles. Fig 3 isa vertical transverse section of boatshowing oscillating receptacles on line a-a Fig. 2. Fig. 4: is a side view of oscillating receptacle or compartment, showing gate operating mechanism, taken on center line Fig. 2. Fig. 5 is a view of the opposite lower side of one of the receptacles. Fig. 6 is a vertical transverse section of theboat on line :c-0c Fig. 2. Fig. 7 is a detail of catch. Fig. 8 isa detail view of floor lever; and Fig. 9 is a detail of the side of receptacle showing one of the slot covers Serial No. 438.878. (No model.)

and detached lugs. Fig. 10 is a perspective view of the elevator box.

In the figures, A is the hull of the boat; B is a longitudinal partition passing through the center of the boat, and serving as a partition between the receptacles, C, 0, formed by cross partitions 0'. These partitions are integralwith or securely fastened to the hull at the sides and to one another, but do not descend completely to the bottom of the hold, but form the sides and end of stationary receptacles, as shown in section in Fig. 6. The lower portions of receptacles are formed of sloping sides, E, inclosing between them tapering spaces terminating in openings E provided with gates at F, through which the material can be discharged, subject to the mechanism shown. The bottoms may be fiat if desired, on one or both sides. It will be seen that the partitions, both central and across the boat, tend greatly to stitten the vessel with her weight of cargo.

Underneath the receptacles run the conveyers G, into which material from the receptacles fails when the gates are opened. These conveyors are actuated from any convenient source of power, as from the engine room and discharge in turn into the vertical elevators H, which discharge into swivels I, and thence are connected with the shore terminals, or discharge overboard, wherever desired.

' G are side boards load.

The horizontal and vertical conveyors com plete a series from the receptacles.

The connection of the horizontal conveyors with the elevators is seen in Fig. 1.

In order to incline the forward end of the conveyer, guides J may be employed to secure the position of the conveyer. The supports for the conveyer may be attached to any convenient point desired.

K are sprocket wheels supporting the ends of the conveyer.

- Ahood L receives the conveyers discharge.

M, is the tower or box in which the elevator travels, and the rear of the box opens by covers M so that any clogging can be relieved.

M is a door or small hatch in the deck, closed when the covers M. are closed.

to prevent spilling the N is an additional. guiding wheel which permits the pansL' of the elevator to bethrown back so that all are completely dumped before passing the swivel spout I. This spout is swiveled at 'i and supported on the swing rod 1 provided with joint 1 and hinge 1 N and N are the upper and lower chain wheels.

The independent receptacles O are shown at the rear of the vessel next to the engine room and do not touch one another or the sides of the vessel but rest upon the scale lever mechanism as heretofore exhibited and described in my former application bearing Serial No. 405,555 and date of application of September 12, 1891. Hence do not require description here. These pockets or compartments are provided with one or more internal shelves or plates P hinged at the side at 19. These shelves are used to adjust the speed of delivery and are supported upon pins Q projecting through circular slots R in the ends of the receptacles.

A swinging locking device is shown at S pivoted at S adapted to receive the pins Q in recesses s at any point desired to give the shelves the proper inclination. Lugs T are employed to fill the space in the slots and prevent the escape of dust or ore. These lugs are provided with overhanging pawls t which engage the racks r and they assist to supportthe pins Q. The shelves are raised or lowered by ropes from above, shown in dotted lines at p in Fig. 3. These ropes may be employed to support the shelves.

' The mechanism for operating the gates is extremely simple and effective and is constructed as follows: U is a main shaft running centrally between the independent receptacles and rotated from the engine room in any convenient manner. On this shaft are sleeved the loose drums a from which cords V connect with the drum levers V of any desired shape, pivoted on supports V on the independent receptacles at W. These levers are provided with projecting arms :0 which support the gates F pivoted at f. When closed as in the normal condition the spring pawls y catch under the arms a: and hold the gates Fclosed. Cords or rods w connect with the engine or operators room and serve to disconnect the pawls when it is desired to open the gate F. When a sufficient amount has been discharged from the receptacle the mechanism employed to return the gate consists in the clutchZ placed upon the shaft upon a spline and adapted to engage the drum u and impart to it the movement of the shaft, upon which the drum to will pullover the lever V and raise the attached arm and the gate which is pivoted at f upon the receptacle. The clutch Z is then thrown out of engagement with the drum u by means of the angular floor lever 1, moving in the bearings 2 and 3, and the link 4 pivoted to the clutch lever at 5, a floor hearing 6 being provided for the lever. A detail of this is shown at Fig. 8. A turn-buckle 9 serves to adjust the length of the augularlever and joints 10 and 11 serve to loosen the vertical arm of the lever 1 when the lever V and arm X are revolved downward so as to give the lever V free movement. A red Z connects the clutch lever with the operating room. mechanism the gate may be opened and closed at the will of the operator.

In Fig. 6 is seen a similar arrangement for the stationary receptacles, which however are completely cleared of their contents and do not require the power mechanism to return the gates to the empty receptacle. In this instance hand reels or drums 12 are employed to close the gates which when released together with the pawls will permit the gates to open of their own accord from the weight upon them. It will be seen that by this method the larger bodies of coal or ore can be discharged at once from the fixed receptacles of known capacity, while the lesser amounts can be discharged from the independent receptacles. 13 are levers pivoted at 14 to supports 15, on the receptacles and serve to oscillate the sides of the pockets 16 hinged at 17. A chain or rope 18 prevents their being drawn down till released.

It will be seen that as a modified form of this invention the partitions formingthe compartments can be supported on the bottom without touching the sides of the hull or may be attached to a hull lining. If the size of the boat requires, the number of longitudinal partitions may be increased to as many as the width of the boat will contain, and the number of the conveyers may be proportionally increased. Again in smaller vessels the central partition may be dispensed with and only one conveyer series will be required.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a vessel for transportation and storage purposes, the combination of receptacles located within the hull and provided with discharge gates underneath their bottoms, shelves in the receptacles adapted to lie at varying angles and a hinged side of the receptacle, substantially as and for the purpose set forth.

2. In combination with receptacles located within a storage or transportation vessel and provided with discharge gates in their bottoms, means for opening and closing the gates consisting of the drum leversV pivoted at W, and provided with projecting arms w, pawls 'y, provided with cords or rods, 00', drums 12 and cords '0 substantially as described.

3. In a transportation vessel the combination of stationary receptacles provided with gates and operating mechanism therefor, pivoted shelves within the receptacles, and means for operating the shelves consisting in lifting cords, pins at the extremity of the shelves,

moving in circular slots in the sides of the re-.

It will be seen that by means of this ceptacle, detachable locking and elosin g lugs,

in the slots, and pivoted guards for. the slots substantially as described.

4. In combination with the receptacles provided with sloping bottoms, shelves P within the receptacles, pivoted at P and provided with pins Q projecting through circular slots in the sides of the receptacle, with means for securing the same atany angle consisting in lugs T provided with pawls t, adapted to engage the racks r and locking bar S, substantially as described.
